Description of the Related Art

Of the five traditional senses, scent is strongly linked to memory. Werecall what we see with poor accuracy after one month, while we rememberwhat we smell with good accuracy after one year. This phenomenon isattributed to the intimate connection between the olfactory bulb and thebrain's limbic system, often referred to as the “emotional brain.”

Recognizing that the sense of smell is the most emotive of our fivesenses, it is a valuable element of brand communications andexperiential marketing. Said differently, scent is very effective indelivering complete, multi-sensorial environments, since it is the mosteffective sense for creating lasting impressions.

Leading companies in industry sectors like hospitality, retail, gaming,real estate, health care, and senior living recognize the power of“scent marketing” and are seeking service solutions for their commercialestablishments that are effective, safe, and easy to use. However,precise, consistent and measurable wide area dispersion of fragranceshas been a significant challenge for early service providers in thisemerging market. Their scent solutions provide widely varyingexperiences as the quality of scent impressions deteriorates over timeand in changing environments.

Some current scent dispersion technologies provide stand-alone solutionsthat are managed locally by on-site employees or local subcontractors.Since the fragrance dispersed by these commercial scent devices is setmanually and often changed over time, it is extremely difficult toensure a consistent level of fragrance within brand standards across alllocations. Common scent dispersion problems include undiagnosedmalfunctioning of dispensers, incorrect dispenser settings, and devicetampering, as well as scent “blindness” which occurs when employees whowork within a scented location, become insensitive to a fragrance,leading them to make unwarranted changes to manual settings.

Given the great variability of conditions across local sites, it is verydifficult to accurately predict the replacement dates for scent “refillcartridges” (elements often used to contain scent oils or other sourcesof fragrances in dispensing systems). As a result, there are many venueswith no fragrance dispersion when cartridges run empty, while othervenues experience wasted scent oil, increased expense, and disposalissues when cartridges are replaced prematurely.

Consequently, current scent solutions deployed in multi-site commercialbusinesses make it difficult for corporate brand executives, local sitemanagers, and maintenance personnel to establish and maintain aconsistent “acceptable” or “approved” scent concentration across theirvenues. Their inability to adequately control the olfactory portion ofbrand identity is a constant source of frustration, as site surveysindicate that a significant fraction of venues on any given day are notdelivering the brand's targeted sensory experience.

There remains a need for a scent management system to provide wide areadispersion of a fragrance in accordance with a desired profile offragrance in a manner that is consistent, precise, and controllable viaa remote or a local network.

SUMMARY

Among other things, the present disclosure addresses these local“compliance” and brand management issues by enabling effective,centralized management of remotely deployed scent systems, including,without limitation, using microprocessor-controlled and networkeddiffusion devices that deliver data streams to a centralized networkoperations center (or NOC), which may be staffed by experiencedoperators using enterprise class software. Through this managed service,and with the help of precise local tools and enabling components,commercial businesses can ensure precise, wide-area fragrance deliverythat is consistent with brand standards over time and across locations.A wide range of enabling components and technologies are disclosedherein for such a scent management system.

In one embodiment, there may be an electrical contact that may need tobe made between the package and the device when the package isinstalled. An electrical feature on the package may contact anelectrical feature on the device. If contact is made, the packagecontents may be dispensed. If contact is not made, the package contentsmay not be dispensed and an alert may be sent over the network.

In an aspect, a scent cartridge for a networked scent diffusion devicemay include a reservoir that holds a liquid and an atomizer headassembly, and an anti-tampering identifier associated with at least oneof the reservoir and the atomizer head assembly, wherein the scentdiffusion from the device is based on a state of the anti-tamperingidentifier. If the scent diffusion device does not recognize theanti-tampering identifier, an alert may be sent over a network, andscent may not be dispensed. If the cartridge is removed from the device,resulting in the device no longer recognizing the anti-tamperingidentifier, an alert is sent over a network. The state of theanti-tampering identifier is changed based on the proximity of thenetworked diffusion device to a specified network zone. In someembodiments, the atomizer head assembly includes an orifice platecontaining a flow restriction orifice for passing compressed gas to bemixed with liquid before passing through an atomizing orifice.

DETAILED DESCRIPTION

In an aspect, the scent management system provides businesses with amanaged service for precise, wide-area fragrance delivery directed atusing scent to deliver memorable brand impressions and exceptionalcustomer experiences. By building intelligence into equipment deployedon customers' premises, and by managing the equipment using a globalnetwork and a centralized set of software applications, the scentmanagement system provides unprecedented quality and control of aremotely managed scent service for customers and ensures that scentmanagement services are efficacious, reliable and consistent. Such ascent management system is capable of ensuring a defined level ofquality based on intelligence built into the system, from the diffuserdevice to the centrally managed network operations center (NOC), whichmonitors device performance across all customers and across all devicesfor each customer. The scent management system is capable of deliveringidentical scent impressions across all locations, if so desired, throughmeasured fragrance output and in-space metering for preciseconcentration. The scent management system provides a managed scentservice that delivers a consistent brand impression through the precise,dynamic control of a network of scent diffusion devices in either aremote or a local fashion. Features of the scent management system, suchas two-way communication with networked scent diffusion devices toreceive data from the devices and to control the devices remotely,coupled with features of the devices, including sensors and/orprogramming to switch between installed packages of fragrance, enablesthe scent management system to be deployed as part of multiple serviceofferings, including self-service and full-service models of operation.In a self-service model, users may select settings for the devices andreceive indications regarding replenishment, such as through a customerapplication. In a full-service model, settings may be selected andmodified by the NOC not just for one location but across as manylocations as required to conform to brand management goals,replenishment alerts may go to the NOC which is then responsible formanaging the replenishment, and the like. Communication with the NOCallows users the confidence that the devices in a space are operating asdesired without having to be hands-on with the devices or with a controlapplication for the device. Of course, the flexibility of the scentmanagement system enables users (such as non-NOC staff) to utilizecontrol applications to monitor and control the scent diffusion devicesas desired. The system enables intelligent, deterministic delegation ofroles, authorities, and permissions across the network of diffusers topreserve brand integrity. Users can control roles, authorities, andpermissions across a hierarchical organization (e.g. parentcompany/corporate, franchise, location) to enable diffusion devicecontrol on a local level, such as on a location basis, or at a corporatelevel, and the like.

The scent management system may be useful not just for scent brandingand delivering consistent scent impressions, but also for odormitigation, odor neutralization, product advertising,aromatherapy/stress reduction, and the like. Other functional benefitswill be described herein.

The scent management system may include one or more diffusion devices.Each diffusion device may contain a processor, such as amicrocontroller, capable of reporting information (telemetry data) aboutdiffuser status via the Internet to one or more Cloud-based businessapplications. The microcontroller may be capable of controlling theunits autonomously, based on control instructions sent by the businessapplications. The business applications store historical data about thediffusion devices, which enables reporting on this data and mining ofthe data in order to improve scent management services. A NOC may beutilized to monitor the health of the end-user diffusion devices, andmay react to alerts by adjusting the settings of the diffusion devices,or by creating a work order (e.g. to roll a truck, e-mail an on-sitecontact, etc.) in order to address a service issue or replenishmentissue. Alternatively, devices may be self-serve, non-NOC managed. Inembodiments, the networked diffusion devices form part of an Internet ofThings.

In an embodiment, the scent management system may include: a diffusiondevice with built-in intelligence enabled by a built-in microcontrollermodule, plus communication abilities enabled by wireless local and widearea network communication modules; and diffusion device networkconfigurations that support the intelligent management of fragrancedispersion, either locally within a fragranced environment, or remotelyby one or more centralized or distributed network operations center(s)(NOCs) staffed by scent system administrators. The scent managementsystem includes business processes enabled by the diffusion devices,deployed within defined scent dispersion network configurations.Throughout this specification, the terms “scent device”, “scentdispersion device”, “diffuser device”, “diffuser”, “scent diffusiondevice”, or “scent diffuser device” may be used interchangeably witheach other and with the term “diffusion device”, except where contextindicates otherwise. It should be understood that the use of scentedliquids in the diffusion device is exemplary of one of the kinds ofliquids that may be used in the scent management system. Indeed, scentneutralization liquids, disinfectant, cleansing or other liquids mayalso be used in the diffusion devices. Throughout this specification,the terms “cartridge”, “package”, and “reservoir” are usedinterchangeably with each other, except where context indicatesotherwise. Various aspects of the scent management system are describedherein. Further, it should be understood that the devices may work todispense any liquid, such as in a gas or vapor colloidal mixture. FIG. 1depicts an exemplary architecture 100 for a scent management system. Inthis embodiment, a master diffusion device 102 is in communication withone or more slave diffusion devices 104 and a server 108, such as acloud server running cloud-based business applications. In thisembodiment, the device 102 communicates with the server 108 to receivecontrol instructions, systems updates, and the like from and to transmittelemetry data and the like to a NOC 118. Communication may be through acellular connection. The devices 102, 104 may be in communication withenvironmental, or have onboard, sensors 110. NOC user devices 114 maycommunicate through the server 108 with the devices 102, 104. A customercontrol device 120 may be used to control the devices 102, 104 throughthe server 108. An advertiser network user interface 112 may be incommunication with the server 108.

In an embodiment, the scent diffusion device may include acartridge-based removable repository for fragrance oil or other liquidto be diffused, and a diffuser that atomizes the fragrance oil intoparticles to deliver targeted and controllable concentration levels ofthe fragrance oil or liquid. The particles may be variously sized, suchas micro-droplets, or large or small aerosol particles. In embodiments,the diffuser results in minimal fallout of particles. The diffuserincludes at least one of a micro-droplet generator, an atomizer, anebulizer, a vaporizer, an evaporative wick, a saturated solid, and thelike.

In an embodiment, the scent diffusion device may include a solid scentmedium cartridge that heat energy, such as from a coil, light bulb,candle, heated blower, convective heat source, or the like, to heat thescent medium in the cartridge, while a fan blows through the medium todistribute fragrance. Controlling the fragrance diffusion remotely mayinvolve controlling at least one of the fan or the heat source.

In embodiments, such as where a scent diffusion device may include awick or other fixed or solid medium, diffusion rate/efficiency orwicking rate/efficiency may be adjusted over time or periodically, suchas by adjusting an aspect or parameter of the operation of a fan. Forexample, the amount of liquid available for diffusion may decrease overtime as the device operates. In some embodiments, the amount of liquidin the device may decrease at a predictable rate, such as at anexponential rate that can be predicted based on a model, such as aphysical or chemical model. As the amount of available liquid decreasesin the device, it may become more difficult to induce diffusion of theremaining liquid from the device. This may be due in part to changes inan aspect or parameter of a fixed medium that is used to aid diffusionover time. For example, a wick may dry up, a solid fragrance cake maydehydrate, or the like. By controlling a parameter of a device that isused to promote diffusion, such as the speed of a fan, adjustments maybe made to address changes in diffusion characteristics. For example,the fan speed in the diffusion device throughout its operation may beadjusted such that it runs slower when a new cartridge of liquid orother fixed medium is placed in the device, and as a result, the wick orother fixed medium may dry out more slowly. Then, as the device operatesand the characteristics of the wick or other solid medium change, thefan may be sped up to obtain a relatively consistent level of diffusionof the liquid from the cartridge or other fixed medium. In someembodiments, the operation of the fan may approximate an elliptoidcurve, an exponential curve, or other function suitable to obtain acontinuous level of diffusion of the liquid. In embodiments, such aswhere the liquid is a fragrance oil, controlling the fan to obtain acontinuous level of diffusion of the fragrance oil may result in asubstantially stable intensity of fragrance over time.

In an embodiment, a piezoelectric device may be used in the scentdiffusion device to cause a vibration in the package, such as viaultrasonic surface wave effects, or through the use of microscopicallyperforated vibrating mesh (VMT). Such vibration may cause an oscillatingmotion and pressure in the liquid within the package and effectatomization of the liquid. The piezoelectric device may be remotelymanaged to control fragrance levels.

Other devices may be used in the system for scent diffusion, such asthose including atomizers with hydraulic spray nozzles, liquid-liquidimpinging atomizers, air-liquid impinging atomizers, airblast atomizers,prefilming atomizers, high voltage electrospray, and the like.

The diffusion device may further include a pump, to enable the venturieffect or otherwise draw the liquid from within the package to enablediffusion, with a controllable duty cycle. The diffusion device mayinclude a fan that aids in distributing the particles. The fan may below noise, such as by use of a low-noise fan or noise cancellingtechnology. The diffusion device enables uniform dispersion of vaporizedfragrance oil throughout an environment using dispersion technologiesthat require minimal heat. Such technologies allow fragrance integrityto be sustained over time.

In some embodiments, the pump may be a conventional air pump or a speedcontrol air pump. With a conventional air pump, the amount of scentoutput may be controlled using a duty cycle, such as, for example, aduty cycle of “on” for 2 minutes and “off” for 4 minutes to provide a33% duty cycle. Given the ability to remotely control pump operation innetworked scent diffusion devices, the voltage driving the pump may beincreased or decreased remotely, such as in a range of roughly+/−20%from a 10V standard, or from 8 V to 12 V. Controlling the voltagedriving the pump enables remote control of the diffusion rate of thedevice, independent of the voltage range and independent of duty cycle.At a given duty cycle, output can be attenuated or augmented by simplyaltering the voltage for the pump. For example, for multiple diffusersdeployed in an environment, assuming that all of the diffusers are setwith the same duty cycle, the voltage driving diffusers deployed insmaller spaces of the environment may be lowered to attenuate outputwhile the voltage driving diffusers deployed in larger spaces of theenvironment may be raised to augment output. In this example, a dutycycle including an “on” portion of 1 minute at a low speed setting mightput out X micrograms per hour, while the same duty cycle portion of“on”for 1 minute at a high speed setting may put out 3X micrograms per hour.Voltage control of the pump enables volumetric control of the devicerunning on a continuous or nearly continuous basis.

Referring now to FIG. 22, an embodiment of a diffusion device isdepicted. In this view, the housing 2202 contains a pump assembly 2204that pumps liquid up out of the reservoir(s) through tubes attached tothe pump and assembled into fittings 2212. One or more valves, such assolenoid valves 2208, 2210, are placed in line in the tubes to turnpumping on and off.

The diffusion device may include a programmable microcontroller modulewith a memory (fixed or removable) for controlling device functionality,such as control of volume, duty cycle, schedule settings, and the like.The diffusion device may include a wireless local area network modulecapable of communicating with other devices within a physical locationvia radio frequency communications including IEEE standards (such as,WiFi, Zigbee, Bluetooth, etc.) Communications protocols that may be usedby the diffusion device include one or more of Zigbee, MiFi, MiWi, DMX,ANT, Z-Wave, Insteon, JenNet-IP, X10, mesh network, visible light,ultrasound, infrared light, IP version 6 (IPv6), such as IPv6 over LowPower Wireless Personal Area Networks (6LoWPAN), and the NeighborhoodExchange Protocol. The diffusion devices may form a machine-to-machinenetwork. The diffusion device may include a removable wireless wide areanetwork (WWAN) module capable of electronic communications with one ormore remote Network Operations Center(s) via, for example, atelecommunication cellular network. References to a “Network OperationsCenter” or “NOC” throughout this disclosure should be understood toencompass a single, centralized center, or a set of multiple distributedcenters. In embodiments, the diffusion device may include communicationstechnology for wired installations. Telemetry data, such asfragrance-level replenishment alert, may be delivered over thecommunications network. Device firmware may be upgradable via thenetwork.

In an embodiment, on the motherboard of the device, connectors may beadapted to configure the communications module readily or to render thecommunications module modular, such that it may be swapped in and outreadily. For example, the device may be manufactured such that at adistributor, retailer, customer, or other downstream site, acommunications module may be installed or swapped. For example, thedevice may be shipped from the manufacturer to the distributor with acellular communications module installed, but upon receipt, a need forWiFi- and Bluetooth-enabled devices may emerge. The distributor may beable to open the devices and swap out the cellular communications modulefor the WiFi-enabled and/or Bluetooth-enabled module. In some examples,the devices may be able to accommodate a plurality of communicationsprotocols such that in this example, the distributor need only to add inthe WiFi and Bluetooth modules to the existing cellular module. In otherembodiments, the communications module may be embodied with firmware,such that capabilities may be modified by a firmware update, such asdelivered over a cellular network via a cellular networkingcommunications protocol, over the Internet or other IP-based network, orthe like. In embodiments the communications module may be embodied in ormay use a field programmable gate array (FPGA), such that it may bere-programmed in the field to meet changing requirements.

The diffusion device may feature “plug and play” ease of installation,with AC or DC power, auto-configuration and NOC “check-in.” Overall, thediffusion device may be light in weight, so the device can hang from atrack fixture or wall, such as 5 lbs. per device.

The diffusion device may include a manual programming interface (e.g.user interface, screen, button, dial, slider, touch pad, keyboard, orthe like) that allows an individual to manually establish and confirmdevice settings. In embodiments, the diffusion device includes a signalthat alerts a user of a device state. The state may relate to a sensedliquid level. The signal may be at least one of a light 1028, a colorindicator, a message on a text screen, a sound, and the like.

In an embodiment, a scent diffusion device may include a processor thatmonitors the scent diffusion device and generates a status, and a userinterface that provides an alert based on the status, wherein the alerttriggers an event. The status may be a clog and the event may be thescheduling of maintenance. The status may be a need for replenishmentand the event may be at least one of the scheduling of replenishment andordering of additional scent. The status may be a tampering and theevent may be turning off the device. The status may be at least one of aclog, a need for replenishment, a tampering, an overheating, a loss ofpower, an operation error, and a damage. The alert may be at least oneof a light 1028, a color indicator, a message, a pop-up, a sound, ane-mail, a text message, and an SMS/MMS.

In an embodiment, one form of the device may operate as a point-of-usescent disperser, installed within targeted fragrance areas. In anembodiment, another form of the diffusion device may be integrated intothe heating/ventilation/air conditioning system of a venue, withfragrance dispersion occurring through the HVAC ductwork or otherventilation system.

In an embodiment, the diffusion device may be embodied in the formfactor of a flameless LED candle.

In an embodiment, the diffusion device may include a tamper-proofclosure. The tamper-proof closure may be at least one of a physical key,a software-based key, a biometric key, a retinal scanner, and the like.Physical features of the package may also make it difficult to betampered with, such as by including at least one of a sonic-welding, aspin welding, a bayonet lock, and the like. On-board sensors may alsowork as an anti-tampering mechanism if contact with the sensors are lostwhile power is still sensed or utilized by the device.

The package for the diffusion device may include physical features foranti-tampering that prevent the package from operating properly in adevice not configured to accept the package. For example, the packagemay include an RFID tag 1208 for identification and the RFID tag must beread correctly or the diffusion device will not function. Reading theRFID tag may be done on-board the device by an integrated RFID reader ormay be done with a separate RFID reader, such as upon installation ofthe package or during a routine inspection. In another example, thepackage may include another identification tag, such as a bar code 1204or QR code 1202, which may be imaged by on-board imaging or a separateimager. The images may be transmitted to the NOC for analysis andapproval or storage. In one embodiment, there may be an electricalcontact that may need to be made between the package and the device whenthe package is installed. An electrical feature (not shown) on thepackage may contact an electrical feature (not shown) on the device, ormating mechanical features (not shown) may be disposed on the packageand device. If contact is made, the package contents may be dispensed.If contact is not made, the package contents may not be dispensed and analert may be sent over the network.

An alert may be sent over a network if the package is removed, such asif the package is removed early (e.g. a liquid level sensor indicatessufficient liquid remaining), removed in spite of general instructions(e.g. removed without a work order, removed by a non-technician), andthe like.

In an embodiment, a method for securing networked scent diffusiondevices may include associating an anti-tampering identifier with areservoir and an atomizer head assembly of a networked scent diffusiondevice 2102, determining if the anti-tampering identifier is present onthe reservoir or atomizer head assembly 2104, blocking diffusion if theanti-tampering identifier is absent, and communicating the absence ofthe anti-tampering identifier to other networked scent diffusion devices2108. In another embodiment, In an embodiment, the method for securingnetworked scent diffusion devices may include associating ananti-tampering identifier with a reservoir of a networked scentdiffusion device, determining if the anti-tampering identifier ispresent on the reservoir, blocking diffusion if the anti-tamperingidentifier is absent, and communicating the absence of theanti-tampering identifier to other networked scent diffusion devices.

In an embodiment, a diffusion device for atomizing liquids may includeat least two reservoirs that hold a liquid, a liquid level sensordisposed in the device, an anti-tampering identifier associated with atleast one of the reservoirs and a switch, and a processor, operativelycoupled to the liquid level sensor, for generating a first signalindicative of the liquid level, a second signal indicative of thepresence of the anti-tampering identifier, and a control instruction forthe switch based on the first and second signals to cause the device toswitch from utilizing one reservoir in the atomizing diffusion device toutilizing a different reservoir in the atomizing diffusion device.

In an embodiment, a method for operating networked scent diffusiondevices in an environment to achieve a scent impression goal may includereceiving an indication at a networked scent diffusion device thatdiffusion from one or more other networked scent diffusion devices isblocked due to a tampering indication 2002, accessing an environmentmodel for the environment, wherein the model includes one or morenetworked scent diffusion devices 2004, and programming a scentdiffusion profile for the environment to be executed by one or more ofthe remaining non-blocked networked scent diffusion devices to achievethe scent impression goal 2008. In certain embodiments, the modelincludes two or more networked scent diffusion devices.

In an embodiment, an atomizing diffusion device may include at least twopackages with liquid disposed in the diffusion device, an anti-tamperingidentifier associated with at least one of the packages, and aprocessor, operatively coupled to the scent diffusion device, thatdetermines a tampering indication based on the anti-tampering identifierand causes a switch between the packages based on the tamperingindication.

In an embodiment, the diffusion device may include a chemical sensor influid communication with the package for detecting the presence of aspecific component in a liquid, such as one disposed within the package.The specific component may be a tracer or tag molecule placed in thepackage, so that when the tag or tracer is detected, the package isauthenticated. Conversely, if the tag or tracer is absent, the packagemay be identified as potentially fraudulent. In embodiments the chemicalsensor may be disposed outside the package, but may be in fluidcommunication with the contents of the package in order to sample theliquid of the package to determine the presence or absence of thespecific tag or tracer component. If the chemical sensor detects thespecific component, and thus authenticates the package, the device mayproceed to operate to diffuse the liquid as described herein. If thespecific component is not detected, various actions may be taken. Forexample, a visual or audible signal may be generated, such as a flashinglight (e.g., an LED) or a beeping sound, or any other visual, auditory,tactile, or other sensor cue that would alert a user or observer of apotential problem, such as cues of various types known to those ofordinary skill in the art. Such a signal may indicate the absence of thespecific component, which may be due to tampering, an incorrect package,a depleted package, an error, or the like. In other embodiments, thesignal take the form of a message, alert, or communication that istransmitted over a network, such as to a central location, anindividual, a manager, a computer, a mobile device, and the like. Incertain embodiments, the chemical sensor may sample the air for thespecific component, and when the component is not present in the air,the sensor may send an instruction over the network to the diffusiondevice to cease operation.

In embodiments, the package may be embodied in a cartridge, a reservoir,a bag, a balloon, a membrane, and the like. Referring to FIG. 4, acartridge for a scent management system includes a liquid reservoir 404and an atomizer head assembly 402, wherein the liquid reservoir ispositioned below the atomizer head. The liquid reservoir has asubstantially cup shaped geometry, and its top edge is joined to theatomizer head assembly, such as by an ultrasonic weld, a twist lock witho-ring seal, or the like. A conduit or tube 408 for the transportationof the liquid in the reservoir is joined to the atomizer head on itsfirst end, and the second end of the tube extends into the liquid 410within the reservoir, preferably extending sufficiently below thesurface of the liquid to maximize the total volume of liquid drawn fromwithin the reservoir as the liquid within the cartridge is depleted.There may be some condensation, but mostly the excess liquid stays instate and drops back into the reservoir.

The atomizer head may have a gas (e.g. air) inlet passage 412 having oneend in fluid communication with a compressed air source. The second endof the gas inlet passage may be in fluid communication with an orificeplate 418 containing a flow restriction orifice 420. In certainembodiments, a venturi may be used in place of an orifice plate. Theorifice plate separates the gas inlet passage from a mixing chamber 422.The mixing chamber may have a wall opposite the orifice plate, theopposing wall having an atomizing orifice 422. Another wall of themixing chamber may have an opening 424 in fluid communication with thetube. The atomizing orifice may be in fluid communication with anexpansion chamber 428. The expansion chamber may be in fluidcommunication with a baffle chamber 430. The baffle chamber may have anoutlet 432 to the surrounding environment to be treated with theatomized liquid.

The operation of the atomizer head may be as follows: Compressed gasflows into the gas inlet passage, through the orifice plate's flowrestriction orifice, and into the mixing chamber. This creates arelatively high-pressure region on the gas inlet passage side of therestrictor orifice, and the gas flow velocity out from the restrictororifice increases and generates a relatively low pressure region on themixing chamber end of the restrictor orifice. The relative low pressuredraws liquid from the reservoir into the mixing chamber through thetube, and the liquid joins the flow path of the gas out of therestrictor orifice creating a mixture of gas and liquid. The gas liquidmixture then passes through the atomizing orifice into the expansionchamber, creating an atomized mixture of liquid and gas. The atomizedmixture of liquid and gas flows into the baffle chamber, and theatomized liquid and gas flows through the outlet into the surroundingenvironment to be treated.

As the atomized mixture of liquid and gas flow though the expansionchamber and baffle chamber, it impinges on the surfaces of the chambersand walls separating the chambers. This results in the removal of asubstantial portion of the larger particles of atomized liquid from theatomized liquid and gas mixture. The larger particles condense back intoliquid and drain back into the reservoir through a weep hole in thepartition between the expansion chamber and the reservoir. Also, anyliquid not completely atomized after the gas and liquid pass through theatomizing orifice drains back into the reservoir through the weep hole.The baffle chamber also acts as a sound level suppressor, muffling thesound of the gas and atomized liquid flow through the atomizer headassembly. The cartridge is inserted into a diffusion device, with thecompressed gas inlet passage coupling with an air fitting 414 to providethe supply of compressed gas to the cartridge.

The package may be used in the diffusion devices described herein butalso in other scent diffusion devices, such as devices that plug into awall outlet.

In an aspect, a package for use with a scent diffusion device mayinclude a reservoir that holds a liquid and an atomizer head assembly,wherein the reservoir is joined to the atomizer head assembly at a topedge of the reservoir and a tube for the transportation of the liquid inthe reservoir, wherein the tube is joined to the atomizer head assemblyon a first end while a second end of the tube extends below the surfaceof the liquid. A gas inlet passage of the atomizer head assembly mayhave one end in fluid communication with a compressed air source and asecond end of the gas inlet passage in fluid communication with anorifice plate comprising a flow restriction orifice. A mixing chamber ofthe atomizer head assembly may be separated from the gas inlet passageby the orifice plate, the mixing chamber having a first wall oppositethe orifice plate comprising an atomizing orifice and a second wallcomprising an opening in fluid communication with the tube. An expansionchamber may be in fluid communication with the atomizing orifice and abaffle chamber, the baffle chamber having an outlet to a surroundingenvironment. A gas flowing into the gas inlet passage through the flowrestriction orifice generates a relatively low pressure region in themixing chamber that causes liquid from the reservoir to be drawn intothe mixing chamber through the tube where it joins the flow path of thegas out of the restrictor orifice creating a mixture of gas and liquidwhich then becomes atomized when it passes through the atomizingorifice. The liquid reservoir may have a substantially cup shapedgeometry. The top edge of the reservoir may be joined to the atomizerhead assembly by one of an ultrasonic weld and a twist lock with o-ringseal.

In embodiments, certain diffusion devices may be capable of dispersingmultiple fragrances or other liquids. In embodiments, the networkedscent diffusion device may include the capability to accept multiplepackages (also known as cartridges or reservoirs) for operation inmultiple configurations. The diffusion device may be able to accept aplurality of packages, such as greater than one package. In one example,the diffusion device has two packages. When one package is depleted ornear depletion, the diffusion device may switch to diffusion from thesecond package. In another example, the diffusion device can accept fourpackages, where two packages house a first scent and the other twopackages house a second scent, so that both the first scent and thesecond scent each have backup packages and the diffusion device canautomatically switch to a new package when one becomes empty or is neardepletion. In embodiments, the combined volume of liquid in the packagesinstalled in the device may be greater than a percentage of the expecteduse in a replenishment service cycle. For example, the combined volumeof liquid may be more than 50% of the expected use in a service cycle.Switching between packages may be done upon sensing when a package isdepleted or near depletion or may be done on some other basis, such asafter an elapsed time, if it is day or night, upon detection of acondition, upon detection of a user, and the like. A switching system isdescribed elsewhere herein.

In another example, the diffusion device may operate with multiplefragrance packages, and each package may house a different note of afragrance chord, wherein the diffusion device may be programmed to blendthe notes to form the fragrance chord. In embodiments, the fragrancechord may be a particular combination of “base,” “mid-” and/or “high”notes. The fragrance chord may be specified by a brand/media campaignspecification.

In order to maintain consistent fragrance in an environment wherefragrance oil in a reservoir may experience some evaporation ordepletion, certain methods may be employed. Fragrance oil is a mixtureof numerous liquids, each with different partial pressures. When usingatomization, components with higher vapor pressures will flash offearlier, and the heavier components will recycle back into the oilreservoir. The net effect is that as the fragrance oil depletes thefragrance chord, or resultant fragrance, will actually change. Onemethod to potentially influence this effect is to shift the duty cycleof the diffuser device (e.g. increase the t in the duty cycle) as theoil level depletes. Knowing the liquid level, either through sensors,direct measurement or estimation, enables applying the correctionfactor, t, to preserve the fragrance chord. Another method may involveleveraging a second cartridge. In this scenario, if the main cartridgeis partially depleted, adding a small amount of the fragrance oilcontained in the second cartridge will add top notes back to thefragrance chord.

In an embodiment, as scent oil is depleted over time in a package of adiffuser device with a scent oil recycling feature, the average size ofthe molecules in the remaining scent oil increases. One statisticalexplanation is that larger molecules of scent oil are more likely tofall back into the package through the recycling feature duringatomization. This change in average molecule size may affect theperformance of the diffuser and may result in a lower rate of scentdiffusion for a fixed duty cycle setting. A process for adjusting theduty cycle of the diffuser device to compensate for this change inaverage molecule size and reduced rate of diffusion may includeincreasing the duty cycle, pump pressure or other diffuser setting whichaffects rate of diffusion. In one embodiment, a liquid level sensor ofthe diffusion device may determine the liquid level remaining in thepackage and a processor of the diffusion device may use the sensedliquid level to modify a diffuser setting as described herein in orderto maintain a desired rate of scent diffusion, a target value of ascent, or a brand management goal. A method may include receiving asensed liquid level in a package of a scent diffusion device, whereinnon-atomized scent oil is recycled back into the package during deviceoperation and adjusting the duty cycle of the diffusion device tomaintain a desired rate of scent diffusion. Adjusting may include atleast one of increasing the duty cycle, increasing the pump pressure,and changing a diffuser setting.

In another example, the diffusion device may be capable of acceptingmultiple packages, and switching between the packages is done inaccordance with a time, such as to deliver a day and a night fragrance.In yet another example, the diffusion device is capable of accepting aplurality of packages, wherein one package includes a scent neutralizerand one or more other packages includes a fragrance, such as thediffusion device can switch to the scent neutralizer as needed or inbetween dispersion of different fragrances. In yet another example, thediffusion device may house multiple packages and the desired package maybe selected remotely. For example, when a guest arrives in a lobby ofthe hotel, they may choose a particular fragrance to diffuse in theirhotel room. The fragrance diffusion may be triggered remotely.Continuing with the example, the guest may have chosen the fragranceahead of time upon booking or sometime prior to arrival, such that thefragrance is triggered when the room becomes available for the guest,when the guest is checked in, when the guest enters the room and issensed by an occupancy sensor or Bluetooth/WiFi sensor, or the like. Inyet another example, the diffusion device may house multiple packagesand the liquids in the packages may be blended prior to diffusion.

In still another example, one of the packages could be a diluent toreconstitute a concentrated fragrance oil, and the blending could bedone at the level of the diffuser. Blending may be programmed to producea scent concentration factor specified by a brand/media campaignspecification. In this example, a plurality of concentrated fragrancesmay be available in the diffusion device (such as in a carousel), andone or more of the plurality of fragrances can be selected fordiffusion.

In a further example, the diffusion device may accept a single usepackage of fragrance, either in addition to the existing dual packageconfiguration or instead of it. For example, a guest in a hotel may beoffered various single use packages of fragrance for selection in alobby that they can install themselves into the diffusion device. Instill a further example, the scent in the package may be provided by acrystal, a powder, or another non-liquid element that is reconstitutedor diluted prior to diffusion.

In embodiments, the fragrance used by the diffusion devices may matchscents to be used in passive scent devices, such as candles, tarts, orgels. The fragrance may be delivered as an oil or as a solid, such as asolid crystal.

Switching between packages may be done using an automated switchingsystem. An automated switching system for a networked scent diffusiondevice housing a plurality of fragrance packages enables a switchbetween packages upon meeting a condition. For example, the conditioncan be the determination that a level of a fragrance in a package islow. In another example, the switch may be done after an elapsed time ina programmed switchover to mitigate scent desensitization. Inembodiments, the device may utilize a FIFO replenishment process.

In embodiments, the switching system employs a valve. In embodiments,the switching system employs a liquid level sensor, such as anelectrical (e.g. conductive, capacitive transmitters to measure thecumulative capacitance which is a function of the amount of liquid andis based on the liquid's dielectric constant, resistive), magnetic (e.g.Hall effect sensor or Hall effect switch), mechanical (e.g. liquid levelfloat that triggers a switch, physical switch, strain gauge), optical(e.g. imaging sensor, liquid level float plus imaging sensor) liquidlevel sensor, hydrostatic sensors (e.g. displacers, bubblers,differential pressure transmitter) to measure the pressure of theliquid, load cells to measure the mass in the package, electromagnetictransceivers that transmit an EM signal at the surface of the liquidwhich reflects back to its receiver with a time delay that is used tocalculate the liquid level (EM could be ultrasonic, laser, radar, etc.depending on the wavelength of the EM signal that is sent and received),or any other liquid level sensor. In one embodiment, the liquid levelsensor may include a floating magnet disposed within a track inside thepackage, wherein as the liquid level changes, the floating magnet movesinside the track. At least one Hall effect sensor or Hall effect switchis disposed outside the package, wherein the Hall effect sensor or Halleffect switch is disposed in such a way as to sense the position of themagnet. In an embodiment, when a particular position of the magnet issensed, which may correspond with a predetermined liquid level, a switchmay be activated that causes a move from a first state of the switch toa second state of the switch. The switch may be used to switch thediffusion device's utilization of one package to utilization of anotherpackage. For example, the switch may be a solenoid switch betweenpackages. In another embodiment, data from the liquid level sensor maybe used to monitor liquid levels inside the one or more packages in thediffusion device and predict when the package(s) will be depleted ofliquid. This prediction may be used in scheduling replenishment servicesso that the diffusion device is never out of liquid. The NOC, a localcontroller, a gateway device, or any of the devices may perform a daysof supply calculation using an algorithm as part of a predictive modelto determine when packages in a device will be depleted. The algorithmmay utilize measured current liquid level and divide that by the averageusage rate per day to determine a number of days of supply remaining.The average usage rate per day may be defined for any time perioddesired. The result of the calculation may be used to schedule an event,such as a just-in-time replacement of a package, the dispatch of areplenishment technician, or the transmission of an alert/email toon-site personnel. The days of supply calculation may also be done usingan estimated liquid level in place of the measured liquid level, whereinthe estimate may be determined based on a duty cycle used by the device,optionally in combination with other historical or modeled dataregarding device operation. The days of supply calculation may alsoutilize information such as a duration of operation, a compressed gasusage, and the like in place of the measured liquid level in order toestimate an amount of liquid remaining. In an embodiment, the liquidlevel sensor for a networked scent diffusion device provides real-timefragrance levels and causes an alert or signal to be generated when thereading from the liquid level sensor indicates a need for replacement ofa package, when an unexpected reading is obtained, and the like. Inresponse to receiving the unexpected reading, a control instruction maybe sent to the device to turn it off or otherwise cease diffusionoperations. If the reading is higher than expected, which may besuggestive of a clog, a control instruction may be sent to the device toswitch to a new package. Alerts or signals in this example andthroughout this specification may be one or more of visual, audio,electronic (e.g. SMS/MMS, text, email, pop-up, etc.), and the like.Throughout this specification, alerts may be sent asynchronously whenthe device reports an event, or if a device stops reporting to the NOCfor a predetermined period. Throughout this specification, an alert maybe triggered whenever a device goes from a non-alert state to an alertedstate. If two of the same alerts are reported in a row, the second alertwill not cause the device to retrigger a new alert—instead it willconsider the alarm still set. Audio alerts may be transmitted through aspeaker of the diffusion device. Visual alerts may be transmittedthrough LED lights of the devices, or the like. In another example,based on the data on the duty cycle and the SCF, a predictive algorithmmay be used to estimate the actual liquid level. A single sensor near anempty level of the reservoir may be used to verify liquid level.

In an aspect, an atomizing diffusion device may include a floatingmagnet disposed within a track inside at least one package with liquidfor the diffusion device, wherein as a liquid level inside the packagechanges, the floating magnet moves substantially vertically along thetrack. The device may further include at least one Hall effect sensor orHall effect switch disposed outside the liquid at a position to enablesensing the position of the floating magnet in the track. The device mayalso include a processor, operatively coupled to the Hall effect sensoror Hall effect switch, for generating a signal indicative of the sensedposition of the floating magnet and a control instruction for a switchbased on the signal and a switch, operatively coupled to the processor,that receives the control instruction from the processor, wherein thecontrol instruction causes the diffusion device to switch from utilizingone package in the diffusion device to utilizing a different package inthe diffusion device. The switch may be a solenoid switch. The device ofclaim may further include a scheduling facility that receives the signaland predicts when the package will be depleted of liquid or determines apackage replenishment schedule. The device may further include a remotecomputer in communication with the processor for receiving the signaland generating an alert if the signal indicates a need for replacementof a package or when an unexpected signal is obtained. The processor maybe adapted to send a signal indicating the switch to the differentpackage in the diffusion device

In embodiments, the switching system employs a sensor that measures thepressure in the package to determine the presence of a vacuum or athreshold pressure/partial pressure. Certain pressure readings may beassociated with a liquid level in the package. When a certainpredetermined pressure reading is obtained, it may cause an alert orsignal to be generated indicating a need for replacement of a package,an unexpected reading, and the like.

In embodiments, the switching system employs a camera or other imagingfacility to monitor the liquid level inside the package. For example,the package may have a transparent portion that may allow a camera toimage the liquid level.

In another aspect, a method of managing scent in an environment mayinclude disposing one or more scent diffusion devices within anenvironment, wherein the scent diffusion devices include acommunications facility that enables transmitting signals to andreceiving signals from a remote computer. The method may further includedisposing at least one sensor within the environment that transmitssensor data to the remote computer and receiving at least one scentparameter for scenting the environment at the remote computer. Themethod further includes controlling, via the remote computer, diffusionof a liquid from a source of the liquid that is in fluid communicationwith at least one of the scent diffusion devices to achieve the scentparameter. In embodiments, it is not diffusion of a liquid but diffusionof a gas. Controlling may include setting or adjusting an operationparameter of the scent diffusion device in response to the sensor data.The sensor data may relate to static parameters or dynamic parameters,such as room volume, room geometry, room area, airflow, presence ofodor-producing materials, presence of odor-sinking factors, lighting,air flow, altitude, traffic flow, occupancy detection (e.g. IR, camera,CO₂ sensor), proximity sensing, detected odor, fragrance level, scentconcentration factor, temperature, humidity, time of day, season,weather event, detection of a VIP/specific individual entering thespace, such as via a smartphone ping, and the like. In certainembodiments, the scent diffusion device(s) may be configured atinstallation to a baseline configuration, based on the static parametersof the installation site. Then, the device would intelligently adjustoutput of scent, based on algorithms that adjust for dynamic parametersor time-changing conditions. Certain static parameters include roomvolume, room geometry, room area, and altitude. With respect to roomvolume, volume calculations may be performed based on measurements takenof the room, for example, using a tape measure or a laser distancemeter, and then adding the volume data into a data structure whichcharacterizes the space in which the diffuser is deployed. This may bedone at device installation to establish the baseline settings for theScent Concentration Factor. With respect to room geometry, geometry maybe determined by taking into account entries, exits and other areas ofpeople movement, as well as from floor plans. Room area may becalculated based on sensor measurements of linear distance betweenwalls. With respect to altitude, the diffusion devices may have aproximity detection capability based on cell phone technology, whichallows the device to “know” where it is located, for example at aspecific longitude and latitude. Given the long-lat information, thenetworked device can inquire from a remote database the specificaltitude of the location where it is located. This altitude informationis then used to adjust device performance, so for example, a lowersetting of scent diffusion would be used at high elevations with“thinner” air, while a higher level of scent diffusion would be used atlower elevations with “thicker” air.

Dynamic parameters include the presence of odor-producing materials,presence of odor-sinking factors, lighting, air flow, traffic flow,occupancy detection (e.g. IR, camera, CO₂ sensor), proximity sensing,detected odor, fragrance level, scent concentration factor, temperature,humidity, time of day, season, weather event, detection of aVIP/specific individual entering the space, and the like.

With respect to airflow, a sensor technology may measure the mass of airflowing through a device (typically a tube) per unit time. The airflowsensor may be a flow or pressure differential sensor, or switch, ortransducer. For a fixed airflow HVAC system, the air flow sensor may bein the form of a switch, which indicates whether air flow is occurringor not, above a certain threshold. That information would be used toturn “on” the scent diffuser when air is flowing, and turn “off” thescent diffuser when air is not flowing. For a variable airflow HVACsystem, the airflow sensor may provide an analog voltage reading, whichindicates the actual level of air flow. This analog signal may be usedto automatically adjust the diffuser output, based on the level of airflow. In such a way, the device is able to increase scent diffusion whenair flow is high and lower it when air flow is low (or stop when airflow is “off”)

With respect to the presence of odor-producing materials, semiconductorsensors may identify air born scent particles, wherein such sensors maybe “tuned” to specific scents. The receptors of these sensors may beable to identify the shape of a scent molecule, or alternatively, are“tuned” to a certain quantum effect of the scent molecules such as itslevel of vibration. Based on the detection of certain known malodorswithin an environment, the diffusion device can change its level orscent or conversely can add a secondary odor remediation orneutralization diffusion which counteracts the malodor. In the case ofthe two-cartridge system, one cartridge contains the desired scentfragrance, while the second cartridge contains the odorremediate/neutralizer, which would be diffused according to apre-programmed response, once a certain malodor is detected.

With respect to the presence of odor-sinking factors, certain types ofmolecules will interact with or bind to scent particles, causing them todrop out of circulation. These odor-sinking factors can be identified inmuch the same way as previously described for malodors, allowing thediffusion device to follow a pre-programmed algorithm in response to thepresence of the odor sinking factor.

With respect to lighting, photodetectors are devices that can sense thepresence of photons. There are a variety of well-known and commerciallyavailable technologies which enable photo-detection, and some which alsoare “tuned” to detect and measure the relative amount of certain typesof photons, which have characteristic wavelengths (red, blue, etc. inthe visible spectrum of lights). The diffusion device has data inputsthat enable it to respond to the detection or absence of light, such as,to turn off scent diffusion when no light is detected. Similarly,lighting systems in theatrical productions can be used to control thescent diffusers, so that the networked scent diffuser will follow theprogrammatic direction of a lighting control system.

With respect to traffic flow, people detectors are sensors that cancount the number of times a person has walked past a specific point. Onedetector is a photoelectric sensor, which detects the number of times abeam of light, which is placed across a space, is broken or interceptedby a person walking past. Another detector is an image or video camera,which uses image processing techniques to determine the number of peoplein a space, as well as their individual dwell times. The diffusiondevice can take information from a traffic flow sensor and automaticallyadjust its scent diffusion, for example, by scenting an area as peopleare arriving, or increasing the scent level to accommodate a largertraffic throughput.

With respect to occupancy detection, these sensors can confirm thepresence of one or more individuals within a space. One approachincludes an image or video camera that uses image processing techniquesto determine the number of people in a space, as well as theirindividual dwell times. The diffusion device can take informationrelated to occupancy and automatically adjust its scent diffusion, forexample, by providing more scent to an area with more as people, orstopping scent from diffusion in an unoccupied room and then beginningdiffusion of fragrance upon the arrival of people.

With respect to proximity sensing, proximity sensors are triggered whena person is directly in front of a particular space, such as in front ofa particular product display. By sensing the presence of a person atthat space, the diffuser is able to provide a scent experience,coordinated with the presentation of the product in the display.

With respect to detection of a VIP/specific individual entering thespace, cameras with facial recognition software can determine thepresence and identity of an individual or individuals, whose facialprofiles have been pre-loaded for comparison. In another embodiment, theVIP/specific individual may be detected via detection of theirsmartphone. The presence of specific people can therefore becommunicated to the device from these sensors, allowing the scentdiffusion device to alter its performance.

With respect to fragrance level, by “tagging” a desired scent fragrancewith a molecular tag, such as a charged particle, a sensor may be ableto identify and determine the concentration of the “tagged” scentparticles within a space. The diffusion device can be set to deliver acertain level of scent concentration within an environment, and usingodor detection of the scent particles which the diffuser is dispensing,can ensure a defined range of acceptable scent level, or “scentconcentration factor” or SCF. When the sensor detects odorconcentrations below the desired SCF, then the diffuser deliversadditional fragrance to achieve the desired concentration. If themeasured concentration is within the defined SCF, then the diffusercontinues monitoring without diffusion. If the concentration is abovethe SCF, the diffuser can continue monitoring without diffusion, or candiffuse an odor sinking formulation which binds with airborne scent andthereby reduces the scent level to within the desired SCF range.

With respect to temperature, the scent diffuser may have multiple waysof measuring temperature. Internal temperature within the diffusiondevice is measured using a thermistor that is present in the electronicsof the device. This thermistor allows the device to communicate theinternal temperature to a remote monitoring center, which can be alertedif internal temperature exceeds a prescribed threshold such as itsrecommended operating range of temperature. Similarly, with remotemonitoring, the device can be pre-programmed to take certain actionunder certain temperature condition, such as, stop dispensing fragranceoil if the temperature is above its operating threshold, or below thefreezing point of the scent oil. External temperature may be measuredbased a thermal sensor (thermistor) mounted on the exterior of thedevice, allowing the diffuser to alter its performance based on changingtemperatures within the environment which is being. The temperature ofthe exterior climate can be retrieved from a remote data structure,based on the geo-code location of the device using its networkconnectivity. The diffuser can react to the exterior temperature of theenvironment, by diffusing alternate fragrances, or by altering the scentconcentration. With all three forms of temperature measurement andtracking data across diffusers using the remote monitoring capability ofthe devices, one can determine the statistical correlation oftemperature to other performance trends, for example, oil consumptionrate over time.

With respect to humidity, a humidity sensor installed within a devicecan detect internal device humidity, one on the exterior of the devicecan determine environmental humidity within the space being fragranced,and geocode and remote data lookups can be used to retrieve the humidityof the local climate. The scent device can react to changes in thesehumidity levels similarly as described for temperature. Similarly, overtime, remote monitoring can be used to evaluate and correlate trenddata, such as how humidity affects the consumption rate of scent oilwithin a diffuser.

With respect to time of day, the diffusers are smart, connected devices,and consequently, accurately know the time. Based on the geolocationdata from the cell phone modem (or network id) of a diffuser in a thescented environment, the device can accurately set its clock to thecorrect local time zone, and automatically adjust for seasonaladjustments in time, with the goal of keeping the diffuser unit intime-sync with the world clock. Since the scent diffuser devices havethe ability to change fragrance output or fragrance type based on scentprograms or play lists, it is critical that the device has an accuraterepresentation of its current time.

With respect to season, the diffuser has the ability to accurately telltime as well as know the current day, week and year, using the sameapproach as described above. Using this knowledge of time, it can beprogrammed for different performance on different days or in differentseasons of the year.

With respect to a weather event, since the diffuser is smart andconnected, local weather conditions can be downloaded to the devicebased on its geo-location. Based on these local weather conditions, thediffusing device can alter its performance based on a predefined set ofrules.

The scent diffusion device may include at least one package containing afragrance oil or at least two packages containing a fragrance oil. Inembodiment, one of the scent diffusion devices is a master node and theother of the scent diffusion devices are slave nodes and receive controlinstructions from the computer through the master node. In thisembodiment, each scent diffusion device can adjust its own controlsettings based on the activities of the other scent diffusion devices.The method may include configuring the scent diffusion devices so that adevice duty cycle for one of scent diffusion devices does or does notoccur simultaneously within proximity to another one of the scentdiffusion devices. The scent parameter may relate to a brand managementgoal. The method may further include determining the total number ofscent diffusion devices to dispose in the environment based on a roomvolume. The method may further include determining one or more locationsto dispose the scent diffusion devices in the environment based on aroom volume. The operation parameter may include at least one of a flowrate of the liquid, a duration of flow of the liquid, a variation in theflow rate of the liquid, an on/off status of the diffusion device, apackage from which to diffuse the liquid, a switch to a differentpackage from which to diffuse the liquid, and the like.

In another exemplary use scenario, the scent dispersion network includesone or more scent node devices and a wide-area network gateway device.In this scenario, the network gateway device performs the communicationand control functions of the scent gateway device, without actuallydispersing fragrance. In this scenario, system administrators in the NOCcontrol the program settings of all networked scent devices, and ensurefragrance dispersion is conforming to commercial brand standards orother parameters. This scenario provides remote and centralizedmanagement of a scent dispersion network via a network gateway devicethat does not dispense fragrance.

In an aspect, a method of managing scent in an environment may includedisposing one or more scent diffusion devices within an environment,wherein the diffusion devices comprise a communications facility thatenables transmitting signals to and receiving signals from anon-fragrance dispensing, wide-area network gateway device. The methodmay further include networking the network gateway device to the scentdiffusion devices, wherein the network gateway device receivescommunication and control functions from a remote computer fordistribution to the scent diffusion devices. At least one sensordisposed within the environment may transmit sensor data to the remotecomputer. At least one target value of a scent parameter for anenvironment may be received at the remote computer. The method mayfurther include controlling, via the remote computer, diffusion of aliquid, from a source of the liquid in fluid communication with at leastone of the scent diffusion devices, to achieve the target value of thescent parameter, wherein controlling includes setting or adjusting anoperation parameter of one or more of the scent diffusion devices basedon the sensor data. In embodiments, it is not diffusion of a liquid butdiffusion of a gas. At least one of the scent diffusion devices receivescontrol instructions from the remote computer and relays controlinstructions to at least one other scent diffusion device. The scentdiffusion devices may relay control instructions in series, in a ring,in a mesh, in a star networking topology, and the like.

In another exemplary use scenario, the scent dispersion network includesone or more scent node devices, a local area network control device, butwithout a wide-area network gateway device. Each scent node device ispaired with a local area network control device, which enables a localuser within a venue to program and control the scent node devicesindependently of a NOC (local control, versus centralized remotecontrol). This scenario enables local management of a scent dispersionnetwork via wireless local area network communication protocols.Examples of local area network control devices include a computer orlaptop with wireless local area network communication capability; asmart phone, pad device, or tablet computer with wireless local areanetwork communication capability; or a purpose built scent controllerdevice with wireless local area network communication capability. Inembodiments, the scent controller device may be a handheld orwall-mounted device for controlling one or more networked scent diffuserdevices.

In an embodiment, a method of managing scent in an environment, mayinclude disposing at least one scent diffusion device within anenvironment, wherein the at least one scent diffusion device comprises acommunications facility that enables transmitting signals to andreceiving signals from a standalone remote control device, receiving atleast one target value of a scent parameter for the environment at thestandalone remote control device, and based on the target value,controlling, via the standalone remote control device, diffusion of aliquid from a source of the liquid in fluid communication with the atleast one scent diffusion device to achieve the target value of thescent parameter. In embodiments, it is not diffusion of a liquid butdiffusion of a gas.

In an aspect, a method of managing scent in an environment may includedisposing one or more scent diffusion devices within an environment,wherein the diffusion devices comprise a communications facility thatenables transmitting signals to and receiving signals from a local areanetwork control device and networking the local area network controldevice to each of the scent diffusion devices, wherein the local areanetwork control device receives communications from and distributescontrol instructions to the scent diffusion devices. The method mayfurther include disposing at least one sensor within the environmentthat transmits sensor data to the local area network control device,receiving at least one scent parameter for scenting an environment atthe local area network control device, and controlling, via the localarea network control device, the diffusion of a liquid or gas, from asource of the liquid in fluid communication with at least one of thescent diffusion devices, to achieve the scent parameter, whereincontrolling includes setting or adjusting an operation parameter of oneor more of the scent diffusion devices in response to the sensor data.The local area network control device may include one or more of acomputer or laptop with wireless local area network communicationcapability, a smart phone, a pad device or tablet computer with wirelesslocal area network communication capability, a purpose built scentcontroller device with wireless local area network communicationcapability, a handheld device, a wall-mounted device, and the like.

In yet another exemplary use scenario, the scent dispersion systemincludes one or more scent node devices, with no wide-area networkgateway device and no local area network control device. This scenarioprovides for the stand-alone operation of a scent node device usingmanual settings, established by a local individual using the userinterface found on each fragrance dispersion device.

In embodiments, multiple master devices may be deployed at a singlephysical location. In embodiment of multi-device installs (master-slaveconfiguration), each device can adjust its own control settings based onthe activities of the other devices. The system may be a coordinatednetwork of devices with “local scent network” level control mechanismsversus device stand-alone control mechanisms. For example, a group ofmeshed dispensers could be configured so that individual device dutycycles do not occur simultaneously within proximity to one another (onedevice waits for the previous one to dispense, so they do not end upoverloading an area with multiple scent devices “firing” at the sametime). Of course, they may also be configured to fire simultaneously. Ineffect, coordination, sequencing, and/or synchronization of meshed scentdevices is controlled dynamically.

In an embodiment, the number and location of scent diffusion deviceswithin an enclosed space may be established based on the volume of thespace but the individual control programs for those devices may be basedon something other than the volume of the space, such as a sensorreading, an area, a linear distance from the device to a target, and thelike. In embodiments, the initial settings for the diffusion devices maybe established in one manner, such as by using room volume, but then mayswitch over to control via a different mechanism, such as byenvironmental adjustments or rate of consumption measurements, and thelike.

In an embodiment, the diffusion devices may operate in a scent-castingmode, wherein the devices are programmed with a linear distance to ascent target location and the level of fragrance that should be at thattarget location. Further considerations may include airflow and tonnageof an HVAC system when programming a scent-casting mode. In ascent-casting mode, the goal is not to fill the space with fragrance,but rather scent a targeted area or audience with the scent brandimpression.

In an aspect, a method of scent casting in an environment may includedisposing a scent diffusion device within an environment, wherein thescent diffusion device comprises a communications facility that enablestransmitting signals to and receiving signals from a remote computer,determining a distance from the scent diffusion device to a scent targetlocation, receiving, at the remote computer, at least one scentparameter for the scent target location, and controlling, via the remotecomputer, the scent diffusion device to achieve the scent parameter,wherein controlling includes setting an operation parameter of the scentdiffusion device based on the determined distance and the scentparameter. The method may further include disposing at least one sensorwithin the environment that transmits sensor data to the remotecomputer, and adjusting an operation parameter of the scent diffusiondevice in response to the sensor data. The sensor data may relate to atleast one of room volume, room geometry, room area, airflow, presence ofodor-producing materials, presence of odor-sinking factors, lighting,air flow, altitude, traffic flow, occupancy detection (IR, camera, CO2sensor), proximity sensing, detected odor, fragrance level, temperature,humidity, time of day, season, weather event, and detection of aVIP/specific individual entering the space (via smartphone ping or thelike). The method may further include adjusting an operation parameterof the scent diffusion device in response to an HVAC tonnage.

Scent casting in an environment may be accomplished using a network ofdiffusion devices, such as scent diffusion devices. A network ofdiffusion devices may be disposed within an environment that eachincludes a communications facility enabling that transmission of signalsto and the reception of signals from a remote computer. One suchreceived signal may be a scent parameter for a scent target location. Adistance from the diffusion devices to the scent target location may bedetermined by any means available for such determination. Via the remotecomputer, the network of diffusion devices may be controlled to achievethe scent parameter. Controlling may include setting an operationparameter of the diffusion devices based on the determined distance andthe scent parameter.

Scent casting may also be implemented using a hotspot in an environment.Such a diffusion device may include a sensor to determine a distancefrom the diffusion device to a scent target location and a firstcommunications facility 1022 that receives control signals from anetwork operations center, the control signals for controlling a scentdiffusion from the diffusion device in accordance with a scentimpression goal and the distance. The device may also include a secondcommunications facility 1024 to communicate data with a mobile device atthe scent target location for consumer engagement, such as to provideconsumers with a coupon, an ad, a survey, a game, or other content.

A ticketing & workflow facility of the NOC may receive alerts from thedevice management and monitoring system and create tickets. Tickets maybe routed, based on rules, to the correct person, or in some cases,rules might automatically trigger some action (e.g., shut down a devicethat is misbehaving, or reboot a device). The ticketing & workflowfacility may be a configured version of a commercial service ticketingsystem.

Managed, networked diffusion devices, where the device is agnostic tothe actual diffusion technology, may be used for generating a consistentscent profile in a wide area/ambient environment in accordance withbrand standards or other parameters. In an embodiment, generating theconsistent scent profile involves consistently neutralizing a malodor inan environment. Generating a consistent scent profile may includemanagement of duty cycle, schedule, fragrance level/fragrancereplenishment, room volume, room geometry, airflow, presence ofodor-producing materials, presence of odor-sinking factors, lighting,temperature, humidity, altitude, traffic flow, occupancy, time of day,inventory of particular “base,” “mid-” and “high” notes in a fragrancechord and other variables relating to the environment. As such, datacollected by or about the device, data based on measurements by sensorson or associated with the device, and data from users may be transmittedto, generated, or used by the NOC in order to facilitate management.These data will be described herein.

Certain data types may be sent from the diffusion devices to the NOC orother user. Data regarding a work schedule, such as duty cycle, dayparts, and the like, may be sent by the diffuser. Object type, such asthe type of diffuser (e.g. Master, Slave, standalone), may betransmitted by the diffuser. The diffusion device may transmit thefragrance name(s) and level(s). For example, the fragrance level may bea value from 0 to 100, with 100 being full and 0 being empty. Thetemperature, in Fahrenheit, Celsius or other units, as well as date andtime may be transmitted. The diffusion device may send an indication ofthe strength of the local wireless link. An array of any error codesthat are currently present on the device may be transmitted. Thediffusion device may transmit the average pump pressure.

The diffusion device may report diagnostic data on a periodic basis,such as weekly/daily, or by forcing the diffusion device into adiagnostic mode, such as via a local keypad or controller, or from theNOC. Data usage may be reported by Master devices, such as cellular datausage.

In an embodiment, a device management & monitoring (DM&M) facility maybe embodied in a user interface that may include configurable dashboardsto enable activities, such as viewing diffusion device telemetry data,viewing maps of diffusion device locations, receiving liquid levelreadings or other gauge/sensor readings, providing control instructionsto diffusion devices, review status of and manage scent operations forone or more networks of scent diffusion devices, receive data fromdevices, receive alerts, view/edit schedules and scent profiles, viewunitless parameter for articulating and displaying a fragrance level,review alerts to replace packages, order new packages and pay on-line,renew subscriptions for scent management services, review system health(e.g. machine down alerts), change permissions for a user, initiate aticket/workflow, assign a service technician, add/remove device from anetwork, add customer/division/store, and the like. In embodiments, amobile application, such as a smartphone or tablet application, mayallow customers to access a mobile version of the user interface.

The user interface may be used to set up and trigger alerts based onvarious criteria and configurable conditions (e.g., low liquid, machinedown, etc.), wherein the NOC may manage the system by exception based ondetected alarms. The user interface may allow customers to view thestatus of their diffusion devices, adjust their settings, or viewhistorical graphs showing the performance of the devices. The userinterface may take data from DM&M and present it in a way that uses thelanguage of fragrance, rather than of devices (e.g., MAC Address, PANnumber). In embodiments, the DM&M facility may be responsible for allcommunication with diffusion devices and may be the only module that canchange diffusion device settings. In other embodiments, WiFicapabilities may be included in the master diffusion device enabling adirect connection to the device.

The user interface may be used to manage and edit the schedules for oneor more diffusion devices independently of one another. That is, thereis the ability for different diffusers at a single site to havedifferent schedules.

A reports page may be used to generate and access reports. An “aboutpage” or introductory page may tell the user about the version number ofthe application, as well as the version number and device types of thevarious devices.

The user interface may include a login screen for entering the user'sUser ID and password and authenticating it. The user interface mayinclude a dashboard page that shows the status of all local diffusiondevices at a summary level. A visual icon representing each diffusiondevice with an indicator for function or status may be included in thedashboard. The user interface may include a diffusion device page thatincludes a list of diffusion devices at the location, with summarystatus and settings (e.g., volume setting, overall diffusion devicehealth, whether it's currently diffusing or not based on duty cycle,status of communications links, and the like). Icons for each diffusiondevice may be presented. A diffusion device status page may be adrill-down page that shows all device status data and settings, such asoverall diffuser health (good, or error+error code and description),diffuser volume/output-level setting (according to program), diffuservolume/output-level setting (according to setting by local customer,possibly overriding the program), liquid fragrance level (based on thesensor reading), time and date according to device clock, health ofcommunication links between various devices and the local server, whichfragrance is playing/being diffused in the diffuser, date and time oflast service, and the like. An edit diffusion device settings page maybe a page where a user can edit a diffusion device's settings and savethe new settings, including the on/off program settings, and thefragrance volume level.

A location control page may allow the user to increase or decrease theoverall output of all diffusion devices in the location. For example, analgorithm, such as a location control algorithm, may execute acalculation that translates a targeted fragrance value (also known as alocal output level) (e.g., between 0-100, between 0-10, etc.) in thelocation to actual device settings for each diffusion device. The userwould adjust only the overall location volume setting, not the settingsfor each diffusion device. The NOC would then calculate and adjust thesettings for each diffusion device needed to achieve the overalllocation volume setting. The local output level represents the outputlevel aggregated across all diffusers. The user interface may presentgraphical arrows for moving the output level up or down. The masterdiffusion device may adjust its own output level and the output level ofits slaves upward or downward, proportionately based on the new setting.If all diffuser settings were the same, the new settings will all be thesame, but if the diffusers had different output settings, the newsettings may be scaled based on each diffuser's original setting. As anexample, the current output level might be 70, based on 3 diffuserswhose output settings are 65, 70, and 75. If the user moves the outputlevel to 80, the new settings may be the original settings multiplied by(80−70)/70, resulting in settings of 74.28, 80, 85.71, respectively. Theabove calculations may be done by customer web services or the NOC andpushed to the individual diffusers.

The location control algorithm may include feedback from one or moresensors in the environment or onboard the diffusion device in making thecalculations, such as feedback from a Bluetooth/WiFi sensor (e.g. todetermine an occupancy), a different occupancy sensor, an altitudesensor, an airflow sensor, a humidity sensor, a light sensor, amotion/occupancy/proximity sensor, a laser distance measure/digitallaser rangefinder, a particle sensor, an olfaction sensor/VOC sensor, animaging sensor/cameras, a scent concentration factor sensor, a clock, atimer, a calendar, a weather sensor, and the like. Modification orgeneration of a scent profile delivered by a network of scent diffuserdevices may be based on one or more sensed parameters, wherein modifyingthe scent profile is done by selection of or adjustment of the diffusionsettings for one or more available fragrances onboard one or morenetworked scent diffuser devices. The sensed parameter may be at leastone of room volume, room geometry, airflow, presence of odor-producingmaterials, presence of odor-sinking factors, lighting, air flow,altitude, traffic flow, occupancy detection (IR, camera, CO2 sensor),proximity sensing, detected odor, fragrance level, temperature,humidity, time of day, season, weather event, detection of aVIP/specific individual entering the space (via smartphone ping or thelike), and the like. In embodiments, the scent profile is aneutralization of a malodor and the fragrance includes an odorneutralizer. Modification or generation of a scent profile delivered bya network of scent diffuser devices may be based on feedback fromautomated air sampling, wherein modifying is by selection of oradjustment of the diffusion settings for one or more of a plurality ofavailable scent modifiers onboard one or more networked scent diffuserdevices. A user may adjust an overall level of fragrance desired in thespace and the NOC or the master diffuser device may determine theadjustment required for the one or more devices, such as slave diffuserdevices. A master diffuser device may adjust its own output level andthe output level of its slaves upward or downward, proportionately basedon the new setting. In an embodiment, the automated air sampling may beautomated malodor sampling and identification, the scent profile may bea neutralization of a malodor and the scent modifier is a neutralizer orfragrance. Adjusting the settings may include selection of a best-fitneutralization/fragrance for dealing with the malodor and determination& execution of a dispersal profile for the neutralizer/fragrance that isneeded to neutralize or counteract the malodor.

In an embodiment, a method may include disposing at least one sensorwithin the environment that transmits sensor data to a remote computer,receiving at least one target value of a scent parameter for theenvironment at the remote computer, and based on the sensor data,controlling, via the remote computer, diffusion of a scent from at leastone scent diffusion device to achieve the target value of the scentparameter, wherein controlling includes setting or adjusting anoperation parameter of the at least one scent diffusion device inresponse to the sensor data.

In an aspect, a method may include receiving at least one remotelysensed scent parameter for an environment at a remote computer 1402, andbased on the sensed scent parameter data, controlling, via the remotecomputer, diffusion of a scent from at least one scent diffusion devicein the environment to achieve a target value of the scent parameter,wherein controlling includes at least one of setting and adjusting anoperation parameter of the at least one scent diffusion device inresponse to the sensed scent parameter data 1404. The sensed parametermay relate to at least one of room volume, room geometry, room area,airflow, presence of odor-producing materials, presence of odor-sinkingfactors, lighting, air flow, altitude, traffic flow, occupancy detection(IR, camera, CO2 sensor), proximity sensing, detected odor, fragrancelevel, temperature, humidity, time of day, season, weather event, anddetection of a VIP/specific individual entering the space (viasmartphone ping or the like). The scent diffusion device may include atleast one package containing fragrance oil or at least two packagescontaining fragrance oil. One scent diffusion device may be a masternode and the other scent diffusion devices may be slave nodes andcontrol instructions are sent from the remote computer through themaster node. At least one of the scent diffusion devices receivescontrol instructions from the remote computer and relays controlinstructions to at least one other scent diffusion device. In thisscenario, the scent diffusion devices may relay control instructions inseries, in a ring, in a mesh, in a star networking topology, or thelike. Each scent diffusion device may adjust its own control settingsbased on the activities of the other scent diffusion devices. The methodmay further include configuring the at least one scent diffusion deviceso that a device duty cycle does or does not occur simultaneously withinproximity to another scent diffusion device. The scent parameter mayrelate to a brand management goal. The method may further includedetermining the total number of scent diffusion devices to dispose inthe environment based on a room volume. The method may further includedetermining one or more locations to dispose the scent diffusion devicesin the environment based on a room volume. The operation parameter mayinclude at least one of a flow rate of the liquid, a duration of flow ofthe liquid, a variation in the flow rate of the liquid, an on/off statusof the diffusion device, a package from which to diffuse the liquid, anda switch to a different package from which to diffuse the liquid.

In an embodiment, a method may include sampling the air in anenvironment to determine the presence of a malodor according to anautomated sampling program, selecting at least one of a neutralizer anda fragrance for a network of scent diffusion devices to diffuse tocounter the malodor, and adjusting an operation parameter of the networkof scent diffusion devices in response to the malodor to diffuse theselected neutralizer or fragrance. Determining may involve measuring anelectrostatic charge.
